coordinating care across time, and both of those have to happen. and, again, there are models there that do that. now, the second point is financing. again, back to joe. shared risk, shared savings probably is where we're going to end up. we have to have providers sharing risk with payers, and with medicare. but you can't just jump over to get there, because we're in the fee for service world, and it doesn't -- you can't just go from here to there. we're paying $20 million a year ourselves to put these teams in place in order to save medicare $2,000 per month, per patient. now, we're willing to make that investment, because we know we'll get, at some point, to shared risk and shared savings, and we're talking with cmmi about doing that, but the little providers out there that aren't integrated systems can't possibly do that.
